CULVERT-MOLD.

Specification of Letters Patent. Patented SQD. 28, 1909.

Application led January 16, 1909. Serial No. 472,704.

'ing application tiled November 7, 1908, and

bearing Serial Number 461,551.

The object of the present invention is t0 provide an improved t'op or cover section for a culvert mold which may be adjusted'in size and also taken apart to permit of its ready re- Inoval from the molded culvert or other structure.

With the above and other objects in view, the invention consists of the novel features of constructionA and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a plan view with parts broken away and in section olE our improved mold; Altig. 2 is a vertical longitudinal section through the saine; ltig. Ii is a. vertical transverse section; and ltig. 1iis a' detail perspective view of two of the angle metal rein toreing and adj usting bars for the mold sections.

In the present embodin'icnt of the invention the mold is especially adapted for use.

as a top or cover member for a culvert mold such as set forth in the application ahoafc referred to, and it is of substantially semicylindrical forni, consisting of two curved and overlapping mold sections l` 2. These mold sections are preferably constructed of t sheet metal and their bottom edges are reinforced by longitudinally extending angle' metal bars 4 suitably secured to their inner faces, as shown uiore clearly in Fig. 3 ot tlie drawings. Said mold sections are also lreinforced by longitudinally curved and tf'ransversely extending angle nictal reml'orcing bars 5 which also serve as means loi' adjustably uniting the mold sections. 'llie bars -5 are arranged in pairs at the ends and at.

one or more intermediate points on tbe mold J :sections and have their longitudinally extending flanges (5 riveted or otherwise secured to the inner faces of said mold sections so that their transversely extending flanges 'T overlap, as seen in Fig. These overlapping ends of the flanges 7 of the several pairs of reinforcing bars 5 are formed with series of openings S adapted to be brought into register with each other to receive longitudinally extending lockiifg rods th Two 'of said rods are preferably provided :rnd they' are of such length :is/to extend 'tlnough all of the bars 5, suitable handles 10being provided at one end, whereby they may .be readily inserted in or removed from the bars 5. It will be noted that the portions of the longitudinally extending flanges 6 of the bars 5 opposite the overlapping portions of the tianges 7, are cut away so that the upper f or inner edges of the sheet metal mold see-v tions 1, 2 may overlap.

In order to connect the lower or bottom portions of the mold sections and hold them in proper spaced relat1o1i, longitudinally extensible connecting members are provided at Vthe ends and at one or more intermediate portions. Each of these connecting meinbers or bars consists of two flat sections 11, 12 with their inner endsl overlapping and formed with longitudinal series of registering apertures 13 to receive bolts. .1-l-. This connection, it. will lie-seen, permits the connecting member or liar to be varied in length according to the iuljustment ol the mold sections upon cach other. 'lhe outer end of the bar 11, has a hinge connection with the mold section '1, preferably, by providing it with an aperture or eye 16 to receive a verticalv pivotI in thev form of a rivet ai'- ranged in the horizontal flange of the longitudinal reinforcing angle liar 4. "lliis pivotal or hinge connection permits 'the lia-r' 1l to swing horizontally. The -outer or free end 'of the other section l2 is shaped to provide a hook 1,7 to engage an eye 1.8 in theform of a staple arranged in the corresponding flange of the opposite liar il, as clearly shown inltigs. '1 and i ofthe drawings.

ln 'using the invention as the top or cover member fora culvert mold, the mold sections l, 2 are adjusted upon each other and secired' in adjusted position by passingr the loclv'iiigrods f) through the registering openings 8` in tli`e-tlanges 7 ot the transverse reinforcing bars 'llie bracing members are'then adjusted in length by means of thev bolts 1liaiid their hooks 17 are engaged with the eyes 18 so that the bottom portions of the llt) two mold sections will beheld in spaced relation. After the concrete or other plastic material from which the culvert or structure is molded, has become set, the hooks 17 are disengaged from the mold section 2 and the rods 9A are Withdrawn so that the mold sections ,1,2 will drop away from the molded culvert and 'may be removed -from the open end of the same.

While the invention has been shown and described as especiallyY adapted for use as the top or cover member of a culvert mold, it will be understood that it may be used by itself as a culvert mold and in other Ways.

Having-thus described the invention what is claimed is:

The herendescribed mold top comprising two segmental plates forming mold sections and having their upper edges overlapped and slidably engaged, longitudinally extending angle metal reinforcing bars upon the lower edges of said plates, transversely extending segmental angle metal reinforcing bars arranged upon the inner faces of said plates and having their overlapping flanges formed with registering openings, longitudinally extending locking rods passed through the registering openings of all of said transverse bars and longitudinally extensible transverse connecting bars detachably uniting the longitudinal reinforcing bars of the mold sections.

' In testimony whereof We hereunto aix our signatures in the presence .of tivo Witnesses.
